ABSTRACT:
A valve device for controlling the flow of a fluid. In a first embodiment, the valve device is designed to control the flow of a fluid, particularly a hot plastic liquid melt. The valve device comprises a first upper plate and a second lower plate with a third plate interposed between the first and second plates. The first and second plates and the third plates are provided with planar surfaces such that sealing gaskets are not required. In addition, the first and second plates are each provided with an annular protrusion, while the third plate is provided with an annular recess on each of the flat faces thereof to accommodate the protrusions on each of the plates in order to reduce the surface area of plate engagement. The first and second plates are each provided with first and second openings which extend through the protrusion, and the third plate is provided with a pair of apertures located through the recesses. The third plate can be shifted relative to the first and second plates such that the openings between the first and second plates become aligned and communicate with the apertures in the third plate. Material flowing through the first openings or the second openings can be proportionally varied by adjusting the position of the third plate. A heat controlling fluid can be introduced into a heat regulating chamber surrounding the portions of the plates and can pass through center portions of each of the plates, thereby ensuring complete temperature control of the fluid passing through the valve.
